"One thing I will say is I've been through divorce. Divorce is hard enough and then to be under a microscope and scrutinized and rumors. It's just a bunch of crap," said Aguilera, who divorced music executive Jordan Bratman in 2010.

She also offed this advice to Shelton and Stefani on dealing with rumors and tabloid fodder:

"Don't read it! ...You don't need to fill your mind or give your energy to any of it. Keep it positive. Do what makes you happy. Do what makes your soul feel good," she said at an event for Verizon's HopeLine Program.

The 34-year-old singer partnered with the campaign to raise awareness about domestic violence.

"I grew up with domestic violence in my home as a child and witnessed a lot," she explained. "The older you get the more you realize the effects that it does take on in your life ... It can just start to deteriorate who you are and your spirit quicker than anything else."

The mother of two says it's definitely a topic she will discuss with her children one day.

"I'm a mom to a daughter now and I guess it directly correlates for me on a personal level," she said. "There's a time and a place and inappropriateness to when things should be said and how they should be said and that time will come. But I always want to provide them the tools necessary to keep themselves safe."

Aguilera is now taping season 10 of the NBC sing-off, which will air next year.
